SOURCE DRIVER CIRCUIT, METHOD FOR DRIVING DISPLAY PANEL AND DISPLAY DEVICE

摘要

The present disclosure provides a source driver IC. A first sub-driver circuit is provided to, within a time period, control polarities of driving voltages for a first subpixel and a third subpixel in pixel units at odd-numbered positions in a pixel row to be reverse to polarities of driving voltages for a second subpixel and a fourth subpixel in the pixel units at the odd-numbered positions in the pixel row, and a second sub-driver circuit is provided to, within the time period, control polarities of driving voltages for a first subpixel and a third subpixel in the pixel units at even-numbered positions to be identical to polarities of driving voltages for the second subpixel and the fourth subpixel in the pixel units at the odd-numbered positions but reverse to polarities of driving voltages for the second subpixel and the fourth subpixel in the pixel units at the even-numbered positions.
